yes. It is a tiny OMAP5 SoC board with 2 or 4GB RAM and ca. 32 GB eMMC and
thrww board-to-board connectors. It has USB(3), SATA, I2C, HDMI, MIPI and

There is a plan to offer it separately with enough documentation. But first we
need to get the Pyra into production.

Well, the Letux Cortex 8 is a tiny AM3358 based Linux board. I had planned
to spin and offer a second version of it, but now the PocketBone came out and
is essentially the same thing (except that I had planned for eMMC). And the
PocketBone comes at an unbeatable low price so that I can't even get the
components cheaper.

So there is no future for the Letux Cortex 8 board and I have added the PocketBone
to the shop: http://shop.goldelico.com/wiki.php?page=Product&product=1057

The Letux-kernel for the Letux Cortex 8 works out of the box for the PocketBeagle.

Well, in my experience it is easier to modularize on schematics level and have
individual boards than designing a perfectly stable and long-lasting interface.
EOMA68 seems to be outdated to me before it is published.

Well, they are more like high-level evaluation boards. Most of these boards are
supported by the silicon vendors of the SoC. Their purpose is to make it known
to a broader public (of engineers). So the SBC doesn't need to be perfect for

Indeed. And we have all tools to get hardware done.
